Prognostic Uncertainties in Cerebral Vascular Disease

Abstract
Of 25 patients with clinical symptoms and anglographlc findings indicative of aortocranlal disease, 12 underwent surgery intended to improve cerebral circulation and the remaining 13 served as controls. The clinical course of both groups was carefully documented and classified into 8 categories according to the sequelae and duration of neurologic manifestations. Critical evaluation of the progress of both groups yielded no unequivocal evidence that the course of the disorder was materially influenced by he operative procedures. The many factors which make it difficult to predict the outcome of cerebral vascular insufficiency in untreated subjects, as well as the effectiveness of various therapeutic modalities, are discussed.
